auxtrace_queues__grow() has two bugs:
1. When idx is UINT_MAX, the caller passes new_nr_queues = idx + 1 = 0.
The function skips growing (since any nr_queues >= 0), returns
success, and the caller accesses queue_array[UINT_MAX] — an OOB
heap write. Fix by rejecting new_nr_queues == 0 up front.
2. The function allocates a new queue_array via calloc and copies
elements from the old array, but never frees the old array. Fix
by saving the old pointer and freeing it after the copy.
Fixes:
